Pod init error tool 'xcodebuild' requires Xcode

It needs to set your CocoaPod and command line tool version, in your Xcode:

Reset (Uninstall & install) cocoa pod:
Execute the following on your terminal to get the latest stable version:

sudo gem install cocoapods

Use keyword --pre to get the latest pre-release:

sudo gem install cocoapods --pre

Once you've latest command line tool installed in your system, set it from Xcode Menu.

Try the same with Terminal App

Install Command Line Tools (using Terminal app):

Change the active directory:

I got this error when I updated my xcode version to 9.1. I fixed the error with the below command. In your terminal just add

Sudo gem install cocoapods --pre

and enter your mac password. Then try with

pod init

I have an another option to solved the issues. because of the issues happened in xcode 9.3, so i have create the project in xcode 9.2 , install the pod. and than after open the project in xcode 9.3 and start work on it.
